This study is a causal impact evaluation of Watch, Play, Learn (WPL), a program by Sesame Workshop that consists of videos that aim to bring playful early learning opportunities to children, especially those affected by conflict and crisis, via mobile phones. This study focused on the effects of WPL math and social-emotional skills content delivered to Venezuelan migrants and Colombian children living in communities in Colombia where families and children face challenges in accessing essential services, including early education. Implementation was led by the Colombia office of Innovations for Poverty Action.

In this third brief in our series, we outline the process and strategies used as we piloted multiple data collection tools that were being considered for use in several large-scale research studies with the Rohingya in Cox's Bazar. This brief aims to provide context and a path forward for future researchers to deliver quality research in this, and other, complex research environments with the ultimate goal of informing the types, design, and delivery of services to support families and foster resilience in these contexts for generations to come.

An estimated 12 million girls aged 15–19 years, and 777,000 girls younger than 15 give birth globally each year. Contexts of war and displacement increase the likelihood of early marriage and childbearing. Given the developmentally sensitive periods of early childhood and adolescence, adolescent motherhood in conflict-affected contexts may put a family at risk intergenerationally. We propose that the specifics of normative neuroendocrine development during adolescence, including increased sensitivity to stress, pose additional risks to adolescent girls and their young children in the face of war and displacement, with potential lifelong consequences for health and development. This paper proposes a developmental, dual-generational framework for research and policies to better understand and address the needs of adolescent mothers and their small children. We draw from the literature on developmental stress physiology, adolescent parenthood in contexts of war and displacement internationally, and developmental cultural neurobiology. We also identify culturally meaningful sources of resilience and provide a review of the existing literature on interventions supporting adolescent mothers and their offspring. We aim to honor Edward Zigler's groundbreaking life and career by integrating basic developmental science with applied intervention and policy.

In just a matter of weeks, the coronavirus disease-2019 (COVID-19) pandemic has led to huge societal public health and economic challenges worldwide. The clinical effects of COVID-19 on young children are uncertain when compared with older age groups, with lower morbidity and mortality rates and no conclusive evidence supporting transmission during pregnancy; however, there is emerging evidence of increasing rates of child hyperinflammatory shock.1-3 Research on the effects of prior pandemics and disasters clearly indicates that there will be both immediate and long-term adverse consequences for many children, with particular risks faced during early childhood, when brain architecture is still rapidly developing and highly sensitive to environmental adversity.

An unprecedented half of the world’s 57 million out of school children live in conflict-affected countries, and 50% of children of primary-school-age are not attending school. In addition, the unauthorized status of many refugees and migrants worldwide is associated with experiences of social exclusion as access to employment and social services are often unavailable or constrained by host-country governments. Children and youth affected by unauthorized or refugee status are also often excluded from services to support healthy development and learning. This chapter presents a process-oriented developmental framework to guide the development and evaluation of interventions that can buffer the effects of social and political upheaval, displacement, and refugee and unauthorized status on children and youth's development. Rigorous evaluations, showing how programs mitigate the risks of displacement or refugee or unauthorized status, could yield great benefits for the fields of humanitarian aid and refugee and migration policy, making the relative dearth of such evidence even more stunning. This chapter reviews the existing literature from rigorous evaluations of interventions to address these issues, discusses the challenge of measurement of risk and protective factors in these contexts with particular sensitivity to cultural variation, as well as how to address cultural factors in the development and evaluation of interventions. The chapter concludes with specific methodological recommendations for a sound research agenda to further improve our understanding of risk and resilience in development of children and youth affected by war, displacement, and refugee or unauthorized status.

While the past decade has seen increased global efforts to develop reliable and valid measures of developmental phenomena for use in diverse populations within and across countries, the UN Sustainable Development Goals (SDG), and in particular the education goal (SDG4) have revealed a dearth of meaningful and valid measures and indicators to monitor countries’ progress toward achieving the 10 SDG4 targets. Developmental science can a) inform the choice of outcomes, processes, and mechanisms that yield the greatest promise in advancing countries ability to formulate solutions; and b) provide guidance on how to measure educational phenomena to ensure maximum policy relevance. Moving forward, developmental science will need to provide rigorous evidence on measures that incorporate the principles of bioecological frameworks on human development and learning to capture the complexity of the multi-level, multi-dimensional, dynamic processes of development and learning that are relevant to achieving SDG4. The chapter concludes with specific recommendations for how developmental scientists can ensure that their research is directly relevant to and can best support the SDG process.

Young children living in conditions of war, disaster, and displacement are at high risk for developmental difficulties that can follow them throughout their lives. While there is robust evidence supporting the need for early childhood development (ECD) in humanitarian settings, implementation of ECD programming remains sparse, largely due to the lack of evidence of how and why these programs can improve outcomes in humanitarian settings. In order to build the evidence base for ECD in humanitarian settings, we review the current state of implementation research for ECD programming (targeting children 0–8) in humanitarian settings, through a literature review and a series of key informant interviews. Drawing from existing frameworks of implementation research and the findings from our analysis, we present a framework for ECD implementation research in humanitarian settings and propose an agenda for future research.
